Sorry,I can't write in Chinese,but my English is poor......There is a little problems in my computer.
First,use the function of FileOpen to open the text file.
Second ,use FileRead function to read file content into a buffer,then you can deal with the buffer....
In the end,use the function of FileClose to close the file......(you may open the file ,but don't close the file in the program early......the problem is here?)
